发明名称 Portable cement mixer
摘要 A portable cement mixer is provided with an improved supporting frame. The supporting frame includes a first, generally triangularly-shaped end frame comprising two upwardly-converging struts and intermediate cross struts. The second end frame comprises a single upright member. A transverse strut connects a central portion of the cross struts of the first end frame with an intermediate portion of the upright strut of the second end frame. The transverse strut is of rectangular cross section but varying in width and thickness from one end to the other. The new supporting frame is of simple construction and is easier to assemble. It is also sturdier and provides a three-point support for the mixer which can be more readily adapted to uneven ground.
